The GUARDIAN Ultraviolet Monitor visually indicates the level of germicidal ultraviolet energy that penetrates the quartz sleeve and water within the water purifier. The use of an ultraviolet monitor is recommended by the United States Public Health Service in “Criteria for the Acceptability of an Ultraviolet Disinfection Unit.”
Fits Sanitron models: S14A, S17A, S23A, S37C, S50C
Fits MightyPure models: MP16A, MP22A, MP36C, MP49C
The GUARDIAN Ultraviolet Monitor will detect reduction of ultraviolet levels due to:
- Fouling or deposits on the quartz sleeve.
- Poor ultraviolet transmission through the water. Color, turbidity, and organic or other impurities in the water can reduce or interfere with the transmission of ultraviolet rays.
- Lamp outage, component or power failure.
- Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use - lamp replacement is recommended once each year.
All GUARDIAN Ultraviolet Monitors provide output sockets for the operation of an optional
solenoid valve or time delay/solenoid valve combination and optional audio alarm.
The GUARDIAN Ultraviolet Monitor is mounted directly onto the water purifier. The sensor probe is installed into the sight port fitting of the water purifi er. The collar on the bottom of the GUARDIAN Ultraviolet Monitor is secured over the sensor probe. Older model water purifiers may require a reducing bushing to properly mount the newer sensor probes. If unsure whether the reducing bushing is required, contact the factory.
